putting a raycast2d from the last position to the current position of a gameobject

Question

i created a bullet that goes pretty fast that it won't react to the collisions. I saw that you can put a raycast2d that puts the line between the last position and the current position of the gameobject.

However, i do not know how to put it in code so does anyone know how to put it in code? thanks in advance

I now have the solution and for the people who would need this in the future the code is this:

 RaycastHit2D hit = Physics2D.Raycast(lastpos, (lastpos - currentpos).normalized * -1, Vector3.Distance(transform.position,currentpos),LayerMask.GetMask("Default"));

idk if the "-1" will work for others but for me it works so yeah!
